An assistant professor in the Georgia Tech School of Electrical and Computer Engineering (ECE), Wang is the director of the Georgia Tech Electronics and Micro-System Lab and is a member of the Georgia Electronic Design Center (GEDC).\u003C\/p\u003E\u003Cp\u003EThe paper is entitled \u0022A +27.3dBm Transformer-Based Digital Doherty Polar Power Amplifier Fully Integrated in Bulk CMOS,\u0022 and the co-authors include Wang\u0027s Ph.D. students Song Hu and Jong Seok Park; Outmane Chlieh, a Ph.D. student advised by ECE Professor John Papapolymerou; and Shouhei Kousai, a senior design engineer at Toshiba Corporation.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EIn the paper, the team proposed a novel digital Doherty polar power amplifier (PA) circuit architecture and implemented it in a standard 65 nm CMOS process. This architecture leverages digital reconfigurability and achieves\u0026nbsp;optimum Doherty active load-modulation operation for maximum PA back-off efficiency enhancement and optimum AM-AM and AM-PM linearization. These desired properties enabled the wireless transmission of high data-rate with drastically enhanced efficiency, and extended battery life in mobile devices.\u003C\/p\u003E\u003Cp\u003EIn addition, the team demonstrated that this digital Doherty architecture can be reconfigured to achieve robust PA performance against antenna load variations. This aspect of the design opens the door for in-field transmitter reconfiguration to ensure optimum wireless transmission under different or even time-varying radiation environments. This digital Doherty PA circuit architecture can also be further extended to other integrated circuit processes to address defense-related applications.\u003C\/p\u003E\u003Cp\u003EThe work presented in this RFIC paper is sponsored by the Toshiba membership in the GEDC and by Toshiba\u0027s in-kind donations of CMOS multiproject wafer fabrication runs.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E***********************\u003C\/p\u003E\u003Cp\u003EPictured in the photo left to right are Hua Wang, Wang\u0027s Ph.D. students Jong Seok Park and Song Hu (first author), and Lawrence Kushner of BAE Systems.
